Start in the cool shade of tall oaks and conifers at Bothe-Napa Valley State Park and enjoy views of lush vineyards and rocky ridge lines on your way to the historic Calistoga Depot. This section of Ridge Trail also shares an alignment with the Napa Valley Vine Trail. Determined trekkers can continue along a passable gap via Lincoln Ave. to the entrance of Robert Louis Stevenson State Park and 21 more miles of connected Ridge Trail.
